Toallwhom it may concern:

Be 1t known that I, HARRY C. GAMMETE'R,

. .a citizen of the United States, residing at Collinwood, in the countyof Cuyahoga and State of Ohio, have invented a certain new and use ul Im)rovement in Ribbon Attachments, of whic 1 the following is a full,clear,

-. and exact description, reference being bad to the accompanyingdrawings.

The ob ect of this invention is to provide simple and EllGOlJlVUmechanism l'or'noldmg the end of a ribbon to a spool.

'- operat'ors hands.

5 ;T he invention is particularly well ads nod for securing inkingribbons to the s ools of printing or ty ewriting machines. t allows theribbon to e secured to its spool in a way which does not necessitate ther viling of the The ribbon may also be disconnected from the spool,whenever desired, in an equally simple and cleanly manner.

The invention comprises l)IOt(ll:V the com- "bination of a spool havinga longitudinal slot through which the end of the ribbon may pass, andmeans on the end of the ribbon ada ted to extend across such slot andthus hol the ribbon to the spool. The invention includes also thecombina tion with a spool having an opening in its barrel of a ribbonhaving means adapted to be passed edgewise through such opening andthereafter turned to bridge the opening.

The invention also includes a ribbon orcvided with securing meansextending along its end to hold the ribbon squarely to the spool.

Other aspects of the invention will appear from the following morespecific description thereof.

"In the drawings, Figure l is a perspective View of the ribbon. spool;Fig. 2 is a perspective View of the ribbon end with my securing 'mernberthereon; Fig. 3-is a cross section on a larger scale through the ribbonspool with the securing member and ribbon in place; Fig. 4 is anenlarged cross section through the securing member and adj acentportionof for example by turning inwardly integral lugs 3) cut out from theheads,'.suoh lugs pass-.

the ribbon.

' As shown in the drawings, A represents the barrel of a tubular 5 001.This spool me be made of sheet metal providedfwith beads B securedthereto n any suitable manner,

ing" into the interior of the barrel and being in either directionbrazed to it. Extending longitudinally of the barrel is a narrow slot at irough which the ribbon and its securing means ma be passed.

C represents the ribbon and D the securing member fastened to the endthereof. This member preferably made of metal and (-1;- tends across theentire end of ribbon. It consists preferably of a sheet of metal bentinto the arc-shaped form SllOWH b bending over the edges toward theintermediate portion and curving the whole strip. Before such bendingtakes place, the end of the ribbon is inserted against theintermediatepor tion (Z of the strip and then one edge 0 i bent over on top of the,ribbon, the lihbon being turned back on to the top of this edge, afterwhich me other edge (1 is bent over /o the ribbon. This leaves theribbon. extending from substantially the mid point of the arcshapedmetal head.

As will be seen, the me al head is narrow in, cross section cry point,which enables it to be very easily passed through the slot e in thespool barrel. this slot, this metal head assumes a position extendingrol Way from the shit, the ribbon pessi- 1' can it through the slot. Itis s cordin l Y onlv nccessarv in mountim the k) u l D 1 ribbon on thespool to tip the metal head on edge drop it through the slot in thebarrel it then assumes a position bridging the slot andsecuring theribbon to the spool. This operation of assembling may thus beaccomplished without the necessity of the operator soiling his tinge s.He does not have to directly touch the ribbon at all but can take holdof one of the projecting sides of the metal head.

.Vhen in place, the ribbon may he'wrzmeed out the spool and more is noprojection on the outside of he spool to inte fere with the perfectwinding oi the When passed tlv'ough ribbon. The metal head extendingacross the end of the ribbon insures it being held squarely and at allpoints o the spool. This latter point is of osrtic in importance withwide ribbons such as are nscdjon the znnlti-v graph. l

it will no noticed that the metal strip is arc'shaped in cross sectioninn n. are of anproximately the radius o? the spool barrel, so that themetal may he snugly on the inner side of the tubular barrel. I

To enable tlie asy removal of the ribbon slot a, so

from the s 001, I provide a transverse opening a in t e barrel, throughwhich a proper tool may be passed to shift the metal head sufficientlyto allow it to pass through the slot. I find a very small transverseslot is sufficient for this purpose. As shown, I preferably make two ofthese slotsextending in opposite directions from the longitudinal v thatthe metal head may be conveniently released whichever direction theribbon is extended.

8.
